View Full Version : Need Advice, 95 Lexus Gs300

04-07-2009, 11:59 AM
Hey guys,
I need some advice, currently in my 95 Gs300 I have replaced the factory 4" speakers with 5.25" Pioneer Coaxials running off the HU. Since the mid bass is horrible I was wondering if I should add some 6*9's in the back(behind the rear seat head rest).

Should I Upgrade to better components up front? I was think of the Pioneer Rev Series.

hmm...odd...i replaced the 4" in my sc400 (nakamichi audio system) with a set of nice Hybrid L4's and have really good midbass.....

04-07-2009, 12:04 PM
It might have to do with the speakers i have, that and the fact that the pioneers are $50/ pair and the hybrid l4 is around $300.

how did you install them? are the speakers securely installed or just place in there? are there gaps around the speaker?

04-07-2009, 12:07 PM
There might be some gaps around the speaker since we tried to install the 5.25" speakers, had to make some modifications.
If there are gaps, how can I seal them?

any rigid material that can be used to cover it, then secured into place....to get good, solid midbass output you need a rigid surface...also make sure you didn't wire speakers out of phase as this can impact midbass output as well......

if you have some laying around...you can close the gaps with sound deadner...

Can I use sound foam, or do I need something like dynomat? What about non hardening modeling clay?

04-07-2009, 12:16 PM
the modeling clay would work nicely, just basically depends on how big your gaps are....

Thanks, I have some left over sound proofing foam as well, could i use that on the doors or would that be a bad idea?

having problems uploading pictures off my brothers mac....sorry

Wow, that looks awesome!! My car is no where near that, mainly because I dont know how to do it my self. i got someone that does it but I doubt we can accomplish all that. All I want is to make sure the speakers are sealed and maybe use some of the sound proofing foam around it.

im sure you guys could do it... just buy some deadener.. maybe like the extreme door kit off ebay..i think i saw the kit for like 57 shipped.dynamat the doors and seal your gaps with the foam your talking about...how do you have the mids mounted,did you modify the stock pods some how or what?

by the way.... great car

I was actually going to get the SC300(pearl white) but deal didint go through, it was my first choice. But then found the gs.As far as the speakers go, we had to cut parts of the original baffle to make the 5.25's fit.

I noticed you have PG RSD's, how do you like them?

i havent had alot of time listening to them yet but tested them for about 10 min. the other day and so far i like them...lots of midbass. i would imagine it will sound even better once the doors all sealed up.

i love my lex's.... first was a 93 ls400 pearl white/silver 2 tone sold that cause i wanted something sporty...got the sc300 5spd about 8 months ago,tryin to do a big single turbo kit in the near future...and when this ones done id like to find a 1stgen gs like yours...our two cars 1stgen sc and gs can be some of the baddest cars on the road imo.you spend any time on clublexus.com...some of those guys have some sick lex's

I am actually on there, havent posted much, but ya, ur right. The minute I drove this I know i had to have it. Especially when you consider that I had been driving nothing but old buicks and cadillacs lol.
Thanks for the advice, this is my game plan
1)dynamat extreme the door panels
2) replace the current speakers with PG RSD 5C
3) add a piece of sound proofing foam behind the speaker
4)seal any gaps with molding clay
I think that about covers it. BTw, do you have 6.5's or 5.25s?

6.5's..... that sounds like a good plan.....those gs's ride so **** smooth man i lovem....they are getting hard to find to....good luck man,i think deadening the doors properly will make a huge difference for you.oh did you read the sticky on door deadening in this section? if not check it out

I know, I live in Houston and there was only 3 that I could find that was in acceptable condition and within a reasonable price range. I almost bought a 96 SC300, pearl white with only 132k, but when i got to the dealership it was gone. Those cars are still in demand.

they really are ....especially with all the parts available now....nothing wrong wih old caddys and buicks though...i used to have a 68 sedan deville and i also had a 96 supercharged riviera so im down with the buicks and caddys too.lol. i grew up on old school chevys first car was a 87 monte ss...wish i never sold it..i still love old school chevys but for an everyday car you just cant beat these lex's theyre luxury,sporty cars you can make very fast for a little bit of money, and theyll run for ever.
